The normal Walker circulation in the Pacific consists of air rising over Indonesia, west winds in the upper troposphere, sinking air off the west coast of South America, and east winds near the surface. A reversed but weaker Walker circulation (and an enhanced Hadley circulation occurs during ENSO years. In the Indian ocean the circulation cell proceeds in the opposite sense (to the normal Pacific Walker cell), with sinking air over cold waters off the Somali coast and a low-level acceleration from west to east along the equator in the lower atmosphere. See Henderson-Sellers and Robinson (1986) and Kraus and Businger (1994).

where T is the temperature (K). The temperature of a black body can be determined from the wavelength of maximum monochromatic radiation using this relation. The maximum emission wavelengths for the Sun and the Earth calculated from this are, respectively, 0.50 m and 11.4 m.
